Histone proteins are ________ in nature.
Options:
Answer:
C
Solution:
Histones are a set of positively charged, basic proteins found in the nucleus of eukaryotic cells.
They are rich in the basic amino acid residues lysine and arginine. Both of these amino acid residues carry positive charges in their side chains.
The positive charge allows histones to bind tightly to the negatively charged phosphate backbone of DNA, facilitating the packaging of DNA into nucleosomes.
